"Pictures at an Exhibition" is a suite of ten pieces for piano composed by Modest Mussorgsky in 1874. The work was inspired by an exhibition of drawings and watercolors by the artist Viktor Hartmann, a friend of Mussorgsky who passed away. Each piece represents a different artwork, capturing the essence and emotion of Hartmann's creations. The suite was later orchestrated by Maurice Ravel in 1922, which helped popularize the work. It features a recurring theme known as the "Promenade," symbolizing the viewer's walk through the exhibition. The music vividly portrays various scenes, including a "Gnome," "The Old Castle," and "The Great Gate of Kiev."
